1206.0416 (Sergei V. Ketov et al.)

Dark Energy Function in Modified Gravity and Supergravity    [PDF]

Sergei V. Ketov, Natsuki Watanabe
We propose new theoretical constraints on the dynamical dark energy function in f(R) gravity and F(R) supergravity theories by demanding the effective scalar potential to be (i) renormalizable and (ii) supersymmetrizable. A model of the hidden sector responsible for spontaneous supersymmetry breaking is also proposed.
